thersia, two or three species in the Philippines, one in Fiji, 
Vavaca, two species in the Fiji and Tonga islands, one in the 
Philippines, and WNaweclea Vorsteri Seem., confined to the Phi- 
lippines, Society, Tonga, Fiji and Samoan groups. Samoa and 
the Philippines: Wauclea Forsteri Seem., above, Carex Graeffeana 
Boeckl., hus simarubaefolia A. Gray (also in Tahiti), Oleandra 
Wiitmeer Bak. (also in Celebes) and 7'mesipteris tannensis Beruh. 
(also in New Zealand and New Caledonia). Tonga and the Phi- 
lippines: Sarcocephalus glaherrimus Mig. (also in Celebes), and 
one species of Discoca/yx, the genus otherwise Philippine, with 
one species extending to Borneo, and one in the Mariannes, 
while from unlocalized points in Polynesia the following spe- 
cies are reported that also are found in the Philippines: Drg- 
opteris invisa O.K., Ficus tinctoria Forst., and Acacia Richer A. 
Gray (also in Formosa). 
From the above discussions it will be seen that the flora of 
the Philippines is a very complicated one, having in it Malayan, 
Himalayan, Chinese, Polynesian and Australian elements, in 
addition to a very high percentage of endemic species. It was 
previously thought that the Archipelago was comparatively 
poor in endemic genera, but this seems not to be the case, as 
at present, including Polypodiaceae, no less than 26 genera are 
endemic. The percentage of endemic species has not been worked 
out for the flora as a whole, but in one paper in which the 
entire flora of a considerable area was considered '), the ende- 
mism was found to approximate 41°/,. Among various genera 
and families recently considered, At/yrium has 46 species ot 
which 382 are endemic, Scitamineae 68 species of which 56 are 
endemic, Loranthus 43 species with 36 endemic, Connaraceae 1% 
species, with 15 endemic, Symplocos 21 species, with 19 endemic, 
Pandanus 24 species, of which 22 are endemic, Freycinetia 24. 
species, all endemic, Quercus 17 species, of which 13 are endemic,
